Investigation of Payne effect in heat protective materials containing microspheres modified by element organic modifiers.
The paper considers the impact of the introduction of alumino silicate microspheres on value
of the effect Payne and physico-mechanical properties of the elastomer compositions used in
the thermal protective materials. It has been shown that the use of pre-modified microspheres
can increase the degree of interaction between the rubber-filler. It is found that increasing the
filler-filler interaction contributes to the formation of additional spatial crosslinks exerting a
reinforcing effect in the coke layer under conditions ablation erosion and breaking of the material
the high velocity gas stream.
